Anyone who's interested:Advance Auto Parts sells a 2 HP 4 gallon compressor for $88. It's got an oil sump and seems to do a great job for me.I have an impact wrench that puts out 700 ft lbs in reverse and didn't have to wait for it to build pressure at all. I removed and installed ALL the lug nuts on all 6 wheels with no problem. Afterward I used my 1" torque wrench and got a reading of 610 lbs.It is a chinese compressor, but I would swear that it is the same as my old one from Porter Cable. I have them side by side and I can't see a difference in the motor or compressor.Cool!DallasPD4103-1085

Hi Dallas,

Would you classify the compressor as noisy, or quiet? or ... ? I'm still looking for a fairly quiet model to use to air up with less noise than running the DD.

Richard,This is a pretty quiet compressor and only take about 45 seconds to one minute to fill the 4 gallon tanks.It's built by Mech Power and is pretty tight.So tight in fact, I had to drop the pressure a few times to get the motor to turn. The piston was that tight.I've used it hard for about a week and a half and it starts on it's own now. It will also sit for two days or more without losing pressure.The crankcase holds about a cup and a hlf of oil.Even though it's direct drive, It still seems pretty tough. We'll see in a month or two.BTB, Advance also sells another compressor for about $10 less.. it's also a direct drive but hasn't got an oil filled crankcase.IHTHDallas

Hi Dallas,

My 12v oiless is noisy but a different kind of noise than a 671, and no smoke. Good for topping off tires and leaking air bags. It is actually easier than stringing a lot of air hose from a fitting to a far corner tire,

I also seem to remember something mentioned about a tankless air compressor - as there is no reason to have a tank on the compressor since the bus is full of tanks. Now if I could find a tankless, quiet compressor, I would be set.

I have a compressor in the bay and another in the trailer.Wouldn't be without them. Used the one in the bay once to help a friend who's air governor stopped working. Ran his generator to power the compressor and hooked the air hose to a bus air line. Kept him aired up from Las Cruces, NM to central Florida. Didn't have to troubleshoot the no air problem until he got home.
